The antiperspirant for the morning your nerves show up early

Some days your body reacts before you do: a nervous meeting, a warm bus, a fast walk to class. This 2.6 oz invisible solid antiperspirant deodorant is listed as Clinical Strength, with protection for stress, heat and activity sweat.

The listing describes this as a Clinical Strength formula and names three kinds of sweat it is designed for: stress, heat and activity. It also states 100 hour sweat and odor protection. That is the maker’s claim, and the listing does not explain how the hours were measured, so read it as a label promise rather than a number you can check yourself.

It comes as an invisible solid in a 2.6 oz size, and the listing says it leaves no white marks on clothing, which matters if your wardrobe is mostly black tops on one rail. The title includes the name Completely Clean, but the listing gives no description of what it smells like, so whether you like the scent is a matter of taste. Hyaluronic acid is included, and the listing says it helps strengthen the skin’s barrier.

What the listing does not state: the active ingredient or its strength, the full ingredient list, or whether it is free of fragrance. It calls the formula gentle on skin, but gives no testing details for that. If you have sensitive skin, check the ingredients on the pack before you buy. Nothing here says how long a 2.6 oz solid lasts in daily use, either.
